I got one of the original ones a couple of years back ... for the same reason .... to speed me up , especially on some hotel ballrooms .
It did on the big rooms , but i find the 2" pipe cumbersome generally ... and i locked the swivel ... because certain carpets would kind of force it sideways , its a bit gimmicky in someways ... it can be useful around furniture but i dont miss it .
For domestic the standard swan neck (westpac ?) that most sell ... with a green glide , is easier on domestics i find .
I see a bit of a trend back to 1.5" being acceptable with newer wands , offered in 1.5 , the devastator , the sapphire , a couple of others , the 1.5 dang was developed , but after his illness im not sure where its at , i think the whole dang side of things is now sold to the wanders guy (mike something ? ) and some else ..
